Voice Monkey works perfectly to display camera video on my Echo 'Shows' using Flows. But if Silk is not shut off, it will sometimes stay open for hours. To circumvent this problem, I use a second Echo device in proximity to each Echo Show that whispers, "Alexa, go home" after a 30 second 'Wait' in the Flow. :-) Adding a Flow option to 'Shut off browser' after a 'Wait' would be more acceptable than my current solution. Using the second Echo to shut off the browser does not work when there is noise in the room which drowns out the "...Go Home" phrase.
